I have a 4TB My Book External Hard Drive I keep all my Music, Pics, Document, Movies, Downloads, etc on. Everything I never want to lose. Sunday I did my monthly computrer cleanup with Ccleaner, ran Malwarebytes, etc and defragged with Defraggler. I seen that my EHD was pretty fragged so Monday before work, I set Defraggler to defrag it and when I got home, it was done but now everything looks corrupt. Nothing will open. I ran chkdsk /r and it finds a ton of bad sectors but never repairs, just hangs eventually and times out. I cannot lose this stuff so;
1. what is the best way to fix bad sectors or can they BE fixed? I d/l'd Glary Utilities but haven't tried it yet. When I open it, I don't see the drive listed, but chkdsk probably has it locked still until I reboot. Also, I noticed that drive is set to exFAT32. I never noticed or I would have reformatted it to NFSC when I first bought it. Or does that not matter?
2, are the files ruined? If I buy another EHD and copy everything over, will they be OK, do you think?
3, should I reboot of a command prompt (If I can figure out how on Win10) and try Chkdsk /r that way?
Anything else I should try?
